ABSTRACT:
A time division multiple access communication system is provided having multiple sub-channels according to known quadrature amplitude modulation techniques. Each sub-channel has a pre-determined time duration and is divided by a pre-determined number of symbol position time divisions. The symbol positions carry sync, pilot and data symbols. Color code information is incorporated into the sync and pilot symbols. The QAM constellation value of the sync symbol is mapped to a color code value. In addition, the sync symbol carries a color code extension which enlarges the color code space.
